The recent signing from Millwall was handed his first Forest goal after a mistake by Crewe keeper Ben Williams in the 1-1 draw at Gresty Road.
Dobie is looking to add to that strike in Wednesday's crucial game at Coventry and said: "I've come here to play up front. At Millwall I was playing on the right wing.
"I came here expecting to score some goals and that is what I am trying to do. It was a bit of relief.
"The fans have been brilliant. A few have stopped me and said we are pleased you have come."
